DRAFT RIGGING.

Application filed February This invention relates to draft rigging for railway cars and more particularly to mechanism for operatively connecting the coupler,

yoke member and dra ft sills and permitting a desired amount of pivotal motion between the coupler and yoke member.

One of the principal features of my invention generally considered,

is to provide a pivotal connection between a yoke and coupler employing a vertical key therebetween, said key being supported by means of a small horizontal cross key which also serves to guide the rear eiid of the coupler,

An object of the invention is to provide a connection between a railway `draft rigging,

vided with a vertical vided with registering wardly extending arms,

coupler and yoke in a the coupler being proslot and the yoke provert'ical slots in its forall of said slots being longitudinally extended with a vertical key passing therebetween, provided for said key.

and supporting means Another object of my invention is the provision of a novel form of railway draft rigging in which a yoke provided of the vertical type is and forinedwith rearwardly flaring vertical slotsl through the forward ends of the arms thereof, the coupler stem being einbraced by said sert ed through responding slot in the ai'ins,

and a vertical key inthe slots in the arms and a corcoupler stem whereby pivotal motion between said coupler and yoke is provided by virtue o yoke.

Another object ision of a novel f the flaring slots in the.

of my invention is the proform of railway draft rigging in which a slotted coupler is pivotally connected to a vertical yoke by means of a vertical key extending through corresponding slots in the yoke and coupler, the slots in the yoke being rearwardly flaring to allow for angling of the key mit pivotal motion of t thereto, and a slotted tween the rear of the coupler and cushioning' `therein and thereby perhe coupler with respect follower provided be mechanism whereby buiiing forces are transmitted from the coupler to said mechanism, said follower being slidably supported with respect to the draft si stantially horizontal key the slot thereof.

lls by means of a subextending through A further object of my invention is the pro vision of a pivotal connection between the coupler and yoke mem rigging, said pivoting bers of a railway draft being accomplished by 24, i925. serial No. 11,239i

means of a vertical key therebetween supported on a horizontal key through the coupler and draft sills, the portions of the yoke where said vertical key passes therethrough being thickened for increasing the bearing area therebetween and dared rearwardly for allowing angling therein, a slotted follower being provided to the rear of said coupler between the same and cushioning mechanism, said follower being supported on a substantially horizontal key passing therethrough, which key carries a plurality of s acing washers for centering said follower an spacing the saine from the cheek plates and center sil s.

Other features of the invention consisting in the construction ofthe several elements, together with their particular arrangement and combination, will become apparent as the description proceeds.

In the drawings illustrating my invention, the scope whereof is pointed out in the claims:

Figure 1 is a horizontal sectional view of draft rigging embodying my invention.

Figure 2 is a side elevation with parts in vertical longitudinal section.

Referring to the drawings in which similar reference characters` serve to designate corresponding parts in the several views, I have shown a coupler 3 connected to a yoke 4 by means of a vertical key 5. For supportin the key 5 as well as the coupler 3 and forwar end of the yoke 4, a horizontal key 6 extending through the slot 7 in the coupler and slots 8 and 9 in the yoke is also provided. It will be noted that this'key 6 extends between the eenter or draft sills 11 and cheek plates 12'w-hich may be rigidly attached thereto, said key extending through slots 13 in said cheek plates.

rl'he vertical key connect ing the coupler and yoke members extends through a slot 14 in said coupler stem with a relatively small amount of play therein. The corresponding slots 15 and 16 in the yoke arms 17 and` 18, respectively, are preferably formed with their forward ends in substantial alineinent with the forward end of the slot 14, the side walls of said slots, however, flaring outwardly to the rear and said slots being slightly longer than the slot 14, thereby allowing more play between them and the key 5 as well as permitting an angling of said key therein. By reason of the angling permitted between the key 5 and the slots 15 and 16, it will be apparent that the coupler 3 connected to said yoke by llo means of the key 5 ia permitted to pivot or angle to a eorre pondi11g degree with i'wpeety to the yoke 1.

'l'he upright' 'or vertical key iS interweted by and supported upon the hori'fontal key t but an additional Supporting 111ea11 may be provided in the form of a carry iron 1.() peer tioned thereunder and supported from the centersillaby111ean ofboltmas illuetratedin the drawing. 'lhia carry iron inay e1'\e s an additional support for the forward end ofthe yoke.` '111e forward end of the coupler may be slidably stuiported, itl desired. upon a Carry iron 21, as is usual.

The rear end ofthe yoke may be adapted to abut against the back stop 22 and a rearwardly disposed carry iron 28 may also be pro4 vided. The rear portion of the coupler ten1 24 is preferably cored at and thtI rear surface crowned, illustrated in Figure l. to lighten the weight thereof, and inereaaefl in depth or provided with top and botty lugs at the extreme end to serve for spacing" the arms of theyoke. Abutting' again t the rear face of the coupler etem is :1 follower block 26 upon which the coupler ia adapted to roekby virtue of the crowned o1f curved rear portion thereof. '111e block t i: :lottel at'27 for receiving a subatantially horizontal key 28 which extends betv'veen the center :"ill"` l1 and cheek plates l2 thereon through slots 29 therein. The A@lots 2t) are pre l'erably alined with the Sloth` 13 and both sets.- 111ay be extended through correspondingr Slots in the draft` sills.

The key '1S preferably carries a plurality of spacing wa yhere 3l which serve to center the follower ltl and space it from the cheek plate.; l2. The follower 2t is centered vertically by being embraced by the forwardly extending armV 17 and 18 of the yoke. Cushioning mechanism illuetrated diagrannnatically by dot and dash lines in Figure 2, is provided between the rearward face of the follower 2t and the loop portion ot the yoke ineinler, a:' is usual.

The arms 1T and 1S where the same are pierced by the l@lots l5 and 1li. are preferably thickened, as shown at 32 and 13 whereby a greater bearing area between Said arms and the vertical key 5 is provided.

By virtue of the foregoing construction I have provided a novel and etlicient pivotal connection between the coupler and yoke members for railway drat't rigging. Although the slots 8 and 9 in the present construction need only be long enough to receive the Small cross key t3 yet they are preferably made al'iproxiniately eight and tl1ree-quarter inches long to take a standard key and allow7 for the g:tandard amount ot`1nove11'1ent in the cushioning mechanienr lllhen draft forces are applied to the counler they are transnntted tird to the vertical ,d and then directly to the thickened portion,`v `l; and 33 of the yoke :1i-nei. i, rarriea4 these draft forceeA te the fff inerhanisin which in turn tra1r- 1ai- 'ioilo'wei jo, key 21S and from the eheel: pla and center .-ill- Till torte'. however, are applied to 1" the key o is relieved of substarti,Av y hurer :1\ the :-'a111e are tranwnue to the follower 2li, through tl" ."fwhen'vf 111erl1ani1n and from thence thread: thtle f1 portion of the yoke totheback 111;123.
